Blow molding is a fabrication method used to form empty plastic components, typically large ones like bottles, barrels, and vehicle parts. The process involves expanding a preform – a small, molten plastic cylinder – with compressed air into a cavity. This inflation presses the plastic against the surfaces of the mold, taking its final configuration. Once the plastic has solidified and settled, the item is ejected and the mold is unlocked for the subsequent cycle, making a relatively fast and affordable production speed.
